Stop guessing which one. Put them side by side.

The grid says what these tools are. This says what builders did about it — one decision per person, changeable whenever you change your mind.

## Master.dev (formerly Frontend Masters) (master-dev)
- URL: https://master.dev
- Category: Learning, communities & starter kits
- Cost: mixed — Individual subscription about $39/mo or $390/yr · 37 percent team discount at 10+ seats · free beginner bootcamp
- What it is: Frontend Masters rebranded to Master.dev in 2026. Over 300 in-depth courses and 24 curated learning paths across frontend, backend, full-stack and AI-assisted coding, taught by engineers from Netflix, Spotify, Microsoft and Stripe, plus live interactive workshops. A free bootcamp covers HTML, CSS and JavaScript for beginners.
- Why builders pick it: Best breadth per dollar if you actually watch it. The 'Coding with AI' and backend paths cover databases, auth and deployment, which is exactly what prompt-to-app tools never teach you.
- Trap: Subscription value depends on watching regularly; one course you finish beats a year of one you do not. Exact prices render at checkout, and the rebrand broke a lot of old frontendmasters.com links.

## AlternativeTo (alternativeto)
- URL: https://alternativeto.net
- Category: Learning, communities & starter kits
- Cost: free — Free · no paid tier · funded by partnerships and optional donations
- What it is: Crowdsourced database of 150,000+ apps and services ranked by more than two million user opinions, filterable by platform, licence, self-hosted and open source. Community rankings sit alongside staff-curated Crew Picks, and anyone can submit apps or reviews.
- Why builders pick it: The honest counterweight to paid AI directories: when a tool doubles its price or kills its free tier, this is where you find the cheaper or self-hostable replacement in one search.
- Trap: Rankings reward long-standing vote counts, so established tools outrank newer ones and coverage of 2026-era agent tooling lags specialist directories.

## Anthropic Academy (incl. Claude Code in Action) (anthropic-academy)
- URL: https://www.anthropic.com/learn
- Category: Learning, communities & starter kits
- Cost: free — Free · every course and certificate, no credit card · account required
- What it is: Anthropic's own course catalog, hosted on Skilljar. Tracks cover Claude 101, Claude Code 101, Cowork, Agent Skills, MCP and the Claude API. Claude Code in Action is the deepest: plan mode, compaction, the rewind menu, hooks, permission modes, headless runs, GitHub Actions review and packaging plugins.
- Why builders pick it: Free, current, and written by the people who ship the tool, so it is right about defaults that blog posts get wrong. Best first stop once you are past single prompts and want longer unsupervised runs.
- Trap: Vendor training: it teaches the Anthropic way and never compares Claude Code with Cursor, Codex or Gemini CLI. Courses change as the product ships, so bookmarked lessons go stale.
